Winter Trend Data - Central Flyway 
Survey conditions in the CENTRAL FLYWAY during the annual winter 
waterfowl survey were generally good. Some trouble was experienced in 
Oklahoma due to fog and low ceilings, and the survey along the east coast 
of Mexico was delayed because of rain. On the whole, however, there is no 
reason to believe that the data obtained were adversely affected by weather, 
or that they are not comparable to the information obtained during previous 
surveys.
